San Francisco lab worker dies from meningitis

Cal/OSHA is trying to determine how a researcher at the San Francisco VA Medical Center contracted meningitis.

The 25-year-old lab tech died from the rare disease, which strikes only about a thousand Americans a year.

The Centers for Disease Control and Prevention is also investigating. It says it's even rarer for someone working in a federal research lab with strict safety protocols to contract a deadly disease like meningitis.
